Explanation
The correct answer is A. Access point.
An access point is a device that extends the wireless coverage of a network by creating a hotspot that allows wireless devices to connect to the network1. An access point can be connected to a router or a switch via an Ethernet cable or a wireless bridge1. By deploying one or more access points throughout a SOHO location, the technician can provide better wireless connectivity and eliminate dead zones or weak signals2.
A managed switch is a device that allows multiple devices to communicate on a network by forwarding data packets based on their destination addresses3. A managed switch can also provide advanced features such as VLANs, QoS, security, and remote management3. However, a managed switch does not improve wireless connectivity, as it only works with wired devices.
A POE hub is a device that provides power and data over a single Ethernet cable to devices that support Power over Ethernet (PoE) technology, such as IP cameras, VoIP phones, and wireless access points4. A POE hub can simplify the installation and placement of these devices by eliminating the need for separate power adapters or outlets4. However, a POE hub does not improve wireless connectivity by itself, as it still requires an access point or a router to create a wireless network.
A Wi-Fi router is a device that combines the functions of a router and an access point, providing both wired and wireless connectivity to a network and the internet. A Wi-Fi router can be used to create a SOHO network, but it may not be sufficient to cover the entire location with a strong and reliable wireless signal. To improve wireless connectivity, the technician may need to add additional access points or use a mesh Wi-Fi system that consists of multiple routers that work together to create a seamless wireless network.
Therefore, an access point is the best option among the choices to improve wireless connectivity throughout a SOHO location.

The best way to complete the upgrade with the least amount of downtime is to clone the HDD to the SSD using cloning software, and then replace the HDD with the SSD. This way, the user does not have to reinstall the operating system and applications, or copy over their data manually. The other options would either take more time or result in data loss or inaccessibility. Verified References: [How to Upgrade Your Laptop's Hard Drive to an SSD].

A laptop's battery is the component that provides power to the laptop when it is not connected to an external power source, such as a wall outlet or a docking station. A laptop's battery can wear out over time, losing its capacity and ability to hold a charge. This can cause the laptop to not turn on or shut down unexpectedly when it is not plugged in .
According to some web search results , some signs and symptoms of a failing laptop battery are:
* The laptop does not turn on or turns off suddenly when it is not connected to an external power source
* The laptop shows a low battery warning or a red X over the battery icon even when it is fully charged
* The laptop takes longer to charge or does not charge at all
* The laptop feels hot or the battery bulges or leaks
To fix this issue, the technician should replace the laptop's battery with a new one that is compatible with the laptop model and specifications. The technician should also dispose of the old battery properly, following the environmental and safety guidelines .
Reinstalling the laptop's operating system, enabling a remote desktop account, or issuing a peripheral set for use in the conference room are not effective solutions for this issue, since they do not address the root cause of the problem, which is the faulty battery. Reinstalling the operating system may erase the user's data and settings, and it may not improve the laptop's performance or power management. Enabling a remote desktop account may allow the user to access their files and applications from another device, but it does not solve the problem of the laptop not turning on. Issuing a peripheral set for use in the conference room may provide the user with an external monitor, mouse, and keyboard, but it does not guarantee that the laptop will work without an external power source.
